Abstract

The invention relates to the field of cutting tools, in particular to a laser cutting machine, which comprises a bedstock, a horizontal support, a screen, a laser head, a dust absorption hopper, a feeding roller mechanism and a plurality of driving rollers. The horizontal support is slidably arranged on the bedstock, the laser head is arranged in the middle of the upper end of the horizontal support, the screen is arranged on an operating portion in the middle of the bedstock, grid nodes of the screen project, a trench is formed between each two adjacent grid nodes, the feeding roller mechanism is arranged at a feeding end of the bedstock, the driving rollers are arranged above the screen of the bedstock and correspond to the feeding roller mechanism, the dust absorption hopper is arranged on the lower portion of the horizontal support, a focusing lens cavity is arranged in the laser head, and a plurality of focusing lens clamping slots are arranged in the focusing lens cavity. As the clamping slots for mounting focusing lenses with different focal lengths are arranged on the laser head, the same cutting machine can be used for conveniently cutting plates with a certain difference in thickness.

Description

technical field

[0001] The invention relates to the field of cutting tools, in particular to a laser cutting machine. Background technique

[0002] There is only one focusing lens in the laser head of the existing laser cutting machine, and the height of the laser head is relatively fixed. However, in the laser cutting operation, it is often necessary to cut steel plates and other materials with different thicknesses. Considering the cutting quality, it is necessary to cut thicker steel plates. A focused laser beam with a longer focal length is required, and a focused beam with a shorter focal length is required to cut thinner steel sheets, so the thickness of the sheet that can be cut by the cutting machine is limited. In addition, the smoke and dust particles generated by the operation of the existing laser cutting machine will affect the working environment, and the feeding process of the existing cutting machine is also relatively inconvenient.
